If I leave them connected in series, the phone does not charge. So, I can charge the enercell fully, disconnect it from the USB-WERK, then use it to charge the phone. The enercell was inexpensive, so I'm going to stop at the next Radio Shack I see and buy one more so I can have one for the phone and one for the Kindle Fire. I will continue to play around with the suggestion from mulveyr about the USB cables. Thanks for the responses, have been very helpful.
I wonder if you've made things too complicated.
Look, the USB-werk is not "designed" for you to add another battery pac.
It has a battery built in to it.
I'd bet any money that your issue is the extra battery and the wrong cable combo.
Yes it can charge another battery but I bet with the combo of the other battery and your phone your pulling too much draw (current) from the USB-werks cache battery.
Please try ditching the battery pack (enercell?) and direct wiring your phone to your USB-werk.
Try the different cables (like the one that came with your phone when you bought it.
